' Claims. (01. 137 -78) This invention relates to new-and usefulimmovements in automatic fluid, dispensing pp ratus and the primaryobject of. the present. invention is to provide a device that willcfficlcntly and automatically supply fluid to a dischar point withoutsupervision. l, 7

Another important obiectoi the present inventlon is to provide a, .fluiddispensing apparatus that-includes electrical as Well as manual meanswhereby the fluid distributed may be controlled. A lurtherobject. of;the present. invention is to provide an automatic fluid dispensingapparatus including a time control mechanism whereby the flow of. fluidmay be regulated for any length of time and at a s l c ed tim A stillfurther aim or the present invention is to provide an apparatus for theforegoing purposes that is simple and practical in construction,cfilcient and reliable in operation, relatively inexpensive tomanufacture. and otherwise well adapted tor the purposes for which thesame is intended,

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings formin part-hereoi, wherein likenumerals refer to like Parts throughout, and in which: I Figure. 1 is afragmentary diagrammatic front elevational view of the presentinvention;

Figure. 2 is a fragmentary side elevational view ofthe distributor valvemeans;

Figurefl is. an' enlarged vertical sectional view taken, on the line 3-4of Figure Figure. 4 is a perspective view of the humidity controlmechanism; 7

. Figure 5 is a perspective-view of the control valve mounted in thedistributor; and,

v Figure 6. is. a longitudinal vertical. sectional view taken on line6--6 of Figure 5.

Referring now to the drawings in detail, wherein for the purpose ofillustration, there is disclosed a preferred embodiment of the presentinvention, the numeral l0 represents asupport onwhich is mounted adistributor housing I2 having a pair of removable end plates l4.

Extending substantially through the center of the housing and journaledin bearings l6 carried by the hub portion 18 provided at the outer facesofplates |4, is a drive shaft 20. v

Mounted on shaft 20 within housing It is the hub 2| of a rotarydisc-like valve member 22, provided with an arcuate slot 24 in its.flanged portion 26, that selectively communicates with a plurality ofoutlet mains 28 carried by .the

distributor housing l.2.. I v

plurality of circumferentially spaced apertures 30 are also provided inmember 22 to prevent entering pressure from looking member 22Qperatively connected to shaft 20. by a clutch mechanism 32, is a speedreduction gear mechanismdesignated generally by the numeral 34, that isoperated by an electric motor36. The clutch mechanism permits the gearmechanism 34 to rotate the shaft 20 in one direction only.

Av supply main 38 for the distributor is interposed between thedistributor and a source or fluid for supplying fluid to thedistributor. This main 3B is provided withv an air buoy or stack 40closed by removablecap 42 that tends to prevent water hammer in the main38., v

Mounted in the fluid supply main 38 is a sol'enoid operating valve 44that is connected'by' electrical lines 48 to a, source of electric powerfor operating the valve in closing and opening the supply main 38.

A by-pass 48 around valve 44 includes a 'manually operated valve 50 formanually regulating the flow of fluid from the main 38 to thedistributor-housing.

Mounted in series with the solenoid valve 44 is a time control mechanism52 for controlling said valve 44. This time control mechanismis alsoconnected in series to motor36 for simultaneously controlling theoperating period'ior said motor and the opening period for valve 44.

Connected in series to the time control mechanism is a mercury controlmechanism designated generally by the numeral 54. This mercury controlmechanism or humidifier 54 includes a canvas belt 56 interlaced withpegs 58 carried byvan anchor'plate 60. One end of the belt is secured toa housing 62 carried by the plate at one end and the other end of belt56 is connected to'a coll spring 64 mounted within housing 62. Thetension of said spring 54 is adjustable by set screws or the like 66. I

Pivotally mounted within the housing 6 is a mercury tube 68 providedwith-an outwardly pro.- jecting' arm in, that is suitably connected tothe spring 64 adjacent the end of belt 56, A stonand support 12 carriedby the housing supports the lower end of tube 68 when the electricalcircuit to the housing and thus these apertures also per- 60 mit a,smooth undisturbed rotation of the valve.

System is open and limits Pivotal movement of the tube within thehousing. v In practical use of the device the humidifier 54 is mountedoutdoors and when the'weather conditions are dry,v the canvas belt iscontracted to over-balance the spring 64 causing the mercury tube totilt toward the belt and closing the cirone of the outlet mains 28 forcausing a time.

regulated flow of fluid through said outlet main.

As the valve continues rotation, opening 24 then communicates withanother of said mains28 for likewise controlling the time now throughthe mains. However, as previously stated should the atmosphericcondition be wet, the humidity cone trol mechanism will automaticallycut oil the solenoid valve 44 so that water or fluid will not be wastedfor sprinkling a lawn or the like.

1701' manual use of the device, the valve' 5ll is turnedon and byrotating shaft 20 by hand wheel 74, the flow of fluid through the outletmains 28 maybe selectively controlled.

Obviously, clutch 32 is disengaged with the gear mechanism 34 so thattheshaft ZOm'ay be conveniently rotated manually without devolving thegearmechanism. 4

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of "the device will bequiteapparent to those skilled. in this art. .Amore detaileddescriptionv is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as,- herein described and the scope of theappended qlaims.
